This is not the first post I wanted to make. I am a long time CZ owner of both hanguns and rifles. On my first trip to the range, I experienced 2 jams in 90 rounds.Ammo was Win white box, 115 gr. On round 2, then around round 60, the trigger remained to the rear. I saw the round almost entering the chamber, and gave the slide rear a good tap to feed the round. No. Dropped the mag, cycled the slide, but it would not return to battery on an empty chamber. I inserted a loaded mag, and it worked normally until the second jam with the same symptoms. I did also fire 10 rds. Of Speer Gold Dot plus p without incident. One more thing. Has anyone had what I would describe as trigger slap on these? My finger was uncomfortable after 10 rounds, and the trigger rebound spring seems very strong. If this was S&W, it would already be for sale, but I have to give this CZ a chance. I'm not aiming to knock this one, as I really want to appreciate another CZ. Ser. # is C29000xx if it matters. Any suggestions would be appreciated. Thanks! PS: Cleaned and lubed prior to firing...
